We divide 418819 by 4
The aim is to understand the frequency of 4 in 418819.

On to step 1:
The number 4 fits into 4 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

Going ahead to step 2:
If we divide 1 by 4, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 4

Let's proceed to step 3:
4 goes into 18 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we take 16 away from 18, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 4

On to step 4:
4 goes into 28 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 1047.0
If we subtract 28 from 28, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 4

Moving on to step 5:
The number 4 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 10470.0
If we take 0 away from 1, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 4

Let's proceed to step 6:
The number 4 fits into 19 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 104704.0
The remainder is 3 after subtracting 16 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 104704.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 104704.75
Subtracting 20 from 20 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 104704.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 104704.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 104704.75 with a remainder of 0.0.
